Description

Rindopepimut (CDX-110) is an injectable peptide cancer vaccine which targets a mutant protein called EGFRvIII present in about 25% to 30% of glioblastoma cases. The vaccine consists of the EGFRv3-specific peptide (a 13-amino acid mutant vIII epitope) conjugated to the non-specific immunomodulator keyhole limpet hemocyanin (KLH). The US FDA granted it Breakthrough Therapy Designation for glioblastoma in Feb 2015.

Mechanism of action

CDX-110 is an investigational immunotherapy that targets the tumor specific molecule EGFRvIII, a functional variant of the epidermal growth factor receptor (EGFR), which is a protein that has been well validated as a target for cancer therapy. This particular variant, EGFRvIII occurs in about 40 percent of Glioblastoma Multiforme (GBM) patients. It was discovered in a collaborative effort between Dr. Bert Vogelstein and Dr Albert Wong at Johns Hopkins University and Dr. Darell Bigner at Duke University. Unlike EGFR, EGFRvIII is not present in normal tissues, suggesting this target will enable the development of a tumor-specific therapy for cancer patients. Furthermore, EGFRvIII is a transforming oncogene that can directly contribute to cancer cell growth. While originally discovered in GBM, the most common and aggressive form of brain cancer, the expression of EGFRvIII has also been observed in various other cancers such as breast, ovarian, metastatic prostate, colorectal, and head & neck cancers. Celldex has exclusive rights to EGFRvIII vaccines and is pursuing the development of CDX-110 for GBM therapy, as well as in other cancers through additional clinical studies.
